Abstract: 1,045,162. Locking nuts. CANNON ELECTRIC (GREAT BRITAIN) Ltd. Sept. 13, 1963 [March 20, 1963], No.11125/63. Heading F2H. [Also in Division H2] On an electrical plug connector (see Division H2) having pin contacts 10, Fig. 1, for co-operation with sockets in a mating element, a nut 18 has a number of spring- loaded detents 28 for coaction with a ring of indentations 30 on a sleeve 17 which fits at one end into a sleeve 15 on which the nut 18 is screw-threaded to draw the sleeves 15, 17 together to retain insulators 12-14, a key 21 welded in the sleeve 15 locating in a slot 22 on the sleeve 17 to prevent relative rotation of the sleeves. The nut is thus locked against vibrational rotation with respect to the malethreaded sleeve 15 by the sprung detent or detents. A similar locking nut 34 is mounted on the sleeve 15 to engage a thread on the electrical mating element which provides sockets for the contact pins 10 while a cadmium-plated washer 38 between the nuts 18, 34 prevents loosening of the nut 34 causing rotation of the nut 18 because it permits slip. The nut 18 has a flange 27, Fig. 1, or a circlip 40, Fig. 4, which bears on a flange 25 of the sleeve 17 (on which flange 25 are formed the detent indentations 30) to draw the sleeves 15, 17 together.

Title: Improvements in and relating to machines having manually-operated selector devices
Filed: 1924-05-06
Abstract: 240,886. Downes, S. C., and Accounting & Tabulating Corporation of Great Britain, Ltd. May 6, 1924. Lock,ing-devices.- In machines, for example, punching, calculating, or typewriting machines, depending for their action on the manual operation of selector devices by means of which data is transferred to the machine, the action of which is to indicate visually or reproduce in mechanical form such data, the operation of transferring data to the machine must be twice performed in agreeof the data in question. In the punching-machine shown in Figs. 1 and 2, blanks 1 fed by a picker 5 actuated through mechanism 4 from a shaft 3 are transferred by rolls 6 between diepla@es against a cord-stop 7 actuated by linkage from the shaft 3. Punches 8 are blocked by pins 60 depressed by set-bars 17 to effect punching when the die-plate is raised. One punch 8 with pin 60 and set-bar 17 is provided for each index position in a card. The set-bars 17 are locked by bars 46 which are locked by a bail 48 on a shaft 49 with lever 50 actuated through a trip-cam 53 by a pin on the carriage. The carriage travels on rails 22 under control of an escapement wheel 27 and pawls 29, 28 connected by levers 32, 34 to a bail 35 extending across bell-cranks 40 actuated by push-wires 41 from the keyboard. The bell-cranks 40 are pinned to flanges 23 jogged at their lower ends to engage the heads of bars 17 and bent to engage notches 25. Data is transferred to the machine column by column from the keyboard and the bars 17 are locked at the end of the travel of the carriage by the lock-bars. The carriage is manually returned and the data is again set up. Should a wrong key be depressed the operator's attention is drawn to the mistake. If the space-key is wrongly depressed the travel of the carriage is interrupted by the lower end of a plunger fouling the upper end of a lever 17 and the bail 55 through links 36, 37 locks the plungers by moving a bail 38 into notches 39. The machine is manually cleared by a bar 55 actuating a bail 48. The punch-control key may be locked during the setting operation by the trip cam 53. In a typewriter with paper carriage mechanically coupled to the carriage the escapement 20 is omitted and each key of the machine controls through parts 41, 40, 42, set-bars 17 arranged so that for each printing position of the typewriter carriage, the carriage is over a particular column of the set-bars. Paper-shields.- The above-described trip cam 53 may be arranged on the first traverse of the carriages to interpose a shield between the platen and ink ribbon, printing being thereby prevented.

Title: Improvements in or relating to electric contacts, particularly for electrically actuated clockwork
IPC: G04C1/02
Filed: 1928-04-19
Abstract: 291,373. Etablissements E. Jaeger. May 31, 1927, [Convention date]. Electric clocks.-The fixed make-and-break contact of an electrically-maintained clock or watch consists of a close-coiled wire spring 24 fixed to brackets 26 by screws 25 which engage with the convolutions of the spring. The coiled spring has a slight curvature and when engaged by the correspondingly curved movable contact 21 (controlled by the armature 9 in conjunction with the pole pieces 11) it yields and the convolutions separate thereby affording a rubbing contact engagement. The clock is driven by a pawl 6 acting on the ratchet-wheel 1 on the return stroke of the armture 9 (to which the pawl is attached) when the electromagnet is deenergized on separation of the contacts 21, 24. The armature, which co operates with the pole pieces 11, is pivotally mounted on a rod 12 and the contact 21 is pivotally mounted on a. spindle 20 supported by brackets 19 depending from a plate 16. A spring 22 between an extension of the contact arm 21 and an extension 23 of the armature-pawl structure serves to drive the pawl on the return stroke. Fig. 4 shows the contact mechanism in the closed position with the armature 9 about to be attracted and move in the direction of the arrow f<2>. This movement carries the lower end of the spring 22 across the dead-centre position, that is, across the pivot 20, whereupon the spring brings back the contact-member to the off position and the movement of its upper end carries the spring back across the line of centres.
